hi, nice work. i'm working on a project which would use an ADC chip of an Atmega8L
microcontroller. A PC would be interfaced via USB for controlling the ADC
card (Atmega + ADC chip) as well as collecting the data. An API and a
library (for Atmega controllers) needs to be developed. (The required
hardware with a USB inerface has already been built). sir i want to know its parameters, which r to be controlled. if u have the necessary code, plz mail me
ankit.ejain@gmail.com
thank u in advance
plz reply soon

hi,
your device looks really impressive

but i think it can only measure dc values?

can u help me how i can build an ac voltmeter??

i was thinking, if the frequency is specified then the rms value can easily be calculated with a single sample and corresponding time by timer.

but most porbably the frequency wont be specified!!!
i also need the device to sense the rms value within less than a millisecond!! but a 50hz signal takes 20ms for a full cycle!!!

Hi sujay,
what kind of problem are you facing? If nothing is getting displayed, check out the RS232 connector connections. Also, while starting hyper terminal keep the 'flow control' as 'none'. If some garbage is getting displayed, check out that the PC baud-rate is matching with that of the microcontroller.

You can process the data inside PC rather than displaying it on hyper terminal, but for that you need to write a program running in PC which is having access of the serial port. Then you can process the received data using that program.

mr. dharmani, i am having trouble interfacing my atmega32 with the PC(using hyperterminal) so that the value read by the ADC is given on the screen....could you please help me out?....is it also possible that I send the value to my computer and the computer processes the value,instead of displaying it on hyperterminal

Hi Avinash,
since I had started with ICCAVR so got habit of it!! It's 'Application Generator' was great for me as I was starting on AVRs. I was bit confused about creating the makefiles in AVR-GCC, so i had dropped it that time.

But yes, I'm now trying to use AVR-GCC as it's free and good support is also available on net.

Thanks for the comment!

Hi,
Nice projects!
Why don't you use AVR-GCC its free, much popular and fantastic?
It integrates tightly with Avr Studio (by Atmel -FREE!) so no need to worry about makefiles or command line. Every thing can be done in GUI with AVR studio.
